Summary

Completed in 1949, this earth dam serves primarily for recreational purposes, providing a storage capacity of 101 acre-feet with a normal storage level of 52 acre-feet. With a height of 34 feet and a length of 500 feet, the dam holds back a surface area of 6.5 acres and has a drainage area of 114 square miles.

Managed by the Georgia Safe Dams Program, the dam has a high hazard potential and a satisfactory condition assessment as of January 2017. It features an uncontrolled spillway and outlet gates, with regular inspections carried out every two years. Although the risk assessment indicates a moderate level of risk, the dam's risk management measures and emergency action plan status remain unspecified.

Situated within the Clayton County of Georgia, Lake Louise Dam presents an intriguing blend of recreational opportunities and environmental considerations. As water resource and climate enthusiasts explore its historical significance and structural attributes, the dam continues to stand as a vital asset in the local landscape, offering both beauty and potential risks that require ongoing monitoring and management.

Condition Assessment

Satisfactory
No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.

Hazard Potential Classification

High
Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
